The Honourable Society of the Inner Temple, commonly known as Inner Temple, is one of the four Inns of Court (professional associations for barristers and judges) in London. To be called to the Bar and practise as a barrister in England and Wales, an individual must belong to one of these Inns. It is located in the wider Temple area of the capital, near the Royal Courts of Justice, and within the City of London.

The Inn is a professional body for many barristers which provides legal training, selection and regulation. It is ruled by a governing council called "Parliament", made up of the Masters of the Bench (or "Benchers"), and led by the Treasurer, who is elected to serve a one-year term. The Temple takes its name from the Knights Templar, who originally leased the land to the inhabitants of the Temple (or Templars) until their abolition in 1312. The Inner Temple was certainly a distinct society from at least 1388, although as with all the Inns of Court their precise date of founding is not known. After a disruptive early period (during which the Temple was almost entirely destroyed in the Peasants' Revolt) it flourished, becoming the second largest Inn during the Elizabethan period (after Gray's Inn).
